There are many countries that are made of migrants. Here's a map showing this, the darker the region, the more migrants there are.

You can see that the US is not the one with the most amount of migrants.
Once again, attempt is being made to treat legal and illegal immigration at equal footing. If you look at the map, you will find that GCC nations such as Saudi Arabia and Kuwait do have a higher proportion of migrants to the population. But the plus point here is that all of them are legal migrants. Illegal immigration is a punishable offense in most of the countries (unlike the case in USA, where illegals are provided with funds from taxpayer money). This is an issue that is present only in the US/EU. And the only reason is lack of enforcement of laws by the left-wing.
I believe that immigration is a problem that is getting out of control for any country, now any country can be seen full of immigrants, the situation with some in the USA is quite disastrous, but I don't know what is happening with the USA? Why does this allow this to continue growing and growing, why don't they do something about it? Why does the rate of people who are going to cause disasters here and do nothing continue to increase, when they have the most effective police systems in the world, the best Intelligence and the best of the best, why do they allow themselves to be taken? I don't understand it, these things are two reasons why a government should be using a strong hand and doing what they should do, I don't understand why things are like this, they have lost control then this is why? or from whom? Perhaps the president is interested in having so many immigrants enter? I remember that one of Trump's policies was that people can enter the country but everything is legal, nothing illegal, and I see that there are many ways to get into the USA, from a jungle to a parole, things that don't add up to me. Others say that the American people are too Ready to work because the average American doesn't want to work, they don't want to do Anything , and that's why they need a superior workforce.
Now, taking into account all the problems of a country , I believe that immigration is one of the least serious problems. I believe that the things here are intended to go beyond, such as security, plans so that they can get out of the immigration problem well. inflation in the USA, is there a president, or well a candidate who has these calculations and a plan to get out of this? because it is very easy for a crash to come, what we know is that there have been very Particular events that have Decreased this statistic, like the covid, like the wars, like the problems of war threats, all of that has greatly reduced the fact that the USA falls in a sharp Decline , that's how things become Evident.
